Answer:

Héctor salió de su casa con 12 euros.

Step-by-step explanation:

Cuando Héctor gastó en la entrada de cine una tercera parte del dinero con el que salió de casa, tenemos:

[tex] C = \frac{1}{3}x [/tex]    (1)

Cuando compró una bolsa de palomitas con la cuarta parte:

[tex] P = \frac{1}{4}x [/tex]    (2)                                  

Entonces al sobrarle 5 euros y relacionando las ecuaciones (1) y (2) con el monto inicial:

[tex] x - C - P = 5 [/tex]

[tex] x - \frac{1}{3}x - \frac{1}{4}x = 5 [/tex]

[tex] x = 12 [/tex]

Por lo tanto, Héctor salió de su casa con 12 euros.

Answer:

y =  [tex]-\frac{1}{6}[/tex] x - 2

Step-by-step explanation:

Given coordinate:

          ( − 6 , − 1 )

Equation of the given line is  6x− y = 7

Unknown:

Equation of the line that passes through the point and is perpendicular = ?

Solution:

A perpendicular line will have a slope that is of negative inverse to the one given;

              6x  - y  = 7

                     -y  = -6x  + 7

                     y  = 6x - 7

According to y= mx + c

 y and x are the coordinates

    m is the slope

     c is the y-intercept

Therefore, the slope of the line  = 6

  Perpendicular to this = [tex]-\frac{1}{6}[/tex]

 The new line will be;

       Let find the intercept;

             -1  =  [tex]-\frac{1}{6}[/tex] x (-6) + c

             -1  = 1 + c

               c = -2

The new line is;

              y =  [tex]-\frac{1}{6}[/tex] x - 2

Answer:

Yes they are similar because of SAS similarity

Step-by-step explanation:

the side lengths are proportional to each other, and the angle in the middle of the sides is the same size, therefore it has Side Angle Side (SAS) similarity.

ΔTSR ~ ΔFEG by the SAS Similarity Theorem

SAS Similarity Theorem states that two triangles with two pairs of proportionate sides and a pair of included angle are similar to each other.

In the image given, the two triangles have:

This means they are similar by the SAS Similarity Theorem.

Therefore, ΔTSR ~ ΔFEG by the SAS Similarity Theorem.

Answer:

The values of [tex]x[/tex] and [tex]y[/tex] are 10 and 14, respectively.

Step-by-step explanation:

According to the figure, we notice that [tex]AB\equiv BC\equiv AC[/tex] and [tex]\angle A \equiv \angle B\equiv \angle C[/tex], concluding that such triangle is equilateral. Since the sum of internal angles within triangle is equal to 180º, then:

[tex]m \angle A = m \angle B = m \angle C = 60^{\circ}[/tex] (1)

If we know that [tex]m\angle A = 6\cdot x[/tex], then the value of [tex]x[/tex] is:

[tex]6\cdot x = 60^{\circ}[/tex]

[tex]x = 10[/tex]

If we know that [tex]AC = 14[/tex] and [tex]AB = y[/tex], then the value of [tex]y[/tex] is:

[tex]y = 14[/tex]

The values of [tex]x[/tex] and [tex]y[/tex] are 10 and 14, respectively.

Answer:

We validate that the formula to determine the translation of the point to its image will be:

A (x, y) → A' (x+4, y-1)

Step-by-step explanation:

Given

A (−1, 4)→ A' (3, 3)

Here:

We need to determine which translation operation brings the coordinates of the image A'(3, 3).

If we closely observe the coordinates of the image A' (3, 3), it is clear the image coordinates can be determined by adding 4 units to the x-coordinate and subtracting 1 unit to the y-coordinate.

Thue, the rule of the translation will be:

A(x, y) → A' (x+4, y-1)

Let us check whether this translation rule validates the image coordinates.

A (x, y) → A' (x+4, y-1)

Given that A(-1, 4), so

A (-1, 4) → A' (-1+4, 4-1) = A' (3, 3)

Therefore, we validate that the formula to determine the translation of the point to its image will be:

A (x, y) → A' (x+4, y-1)

Answer: 7 - (-5)+12

Step-by-step explanation: best I can put it

(-5) - (-12) = 7 . Option b,c, and d are correct.

Subtraction is a mathematical operator which gives diffrence between two numbers.

Given expression is,  (-5) - (-12)

                                 = -5 +12

                                 = 7

Absolute difference between -5 and -12 is equal to 7.

And, absolute difference between -12 and -5 is equal to 7.    

Also,                          (-5) + 12 = 7  

Hence, expressions with value = 7 are correct.

Answer:

  A.  y = 2/3x - 2

Step-by-step explanation:

The line intersects the y-axis at -2, so eliminates choices B and D, which have y-intercepts of +3.

The line has a rise of 2 grid squares for a run of 3 grid squares, so has a slope of ...

  m = rise/run = 2/3 . . . . . eliminates choice C

The appropriate choice is the one with a slope of 2/3 and a y-intercept of -2:

  A.  y = 2/3x - 2

Answer:y=9x-7

Step-by-step explanation:

Answer:

y = 9x - 7

Step-by-step explanation:

Slope-intercept form is y =  mx + b

Y-intercept is where x = 0. In this instance, when x = 0, y = -7 (0, -7)

So at this point we know b = -7.

Then, take one of the values of x, such as 1, as well as the corresponding value of y and plug in. When x = 1, y = 2 (1, 2)

2 = m(1) - 7

Solve for m (slope)

2 = m - 7

Add 7 to both sides to get m alone.

9 = m

Now we know the slope, and the y-intercept, so we can fill in the equation for slope-intercept form for this linear function.

y =  mx + b

y = (9)x + (-7)

y = 9x - 7

Answer:

Answer:The rate of the slower hiker is 2.2 mph and the rate of the faster hiker is 5.5 mph

Explanation:

One hiker walks 3.3 mph faster than the other.

Suppose, the speed of the slower hiker is  mph.

So, the speed of the faster hiker will be:  

Both hikers are walking toward each other and meet in 10 hours.

We know that,  

So, the distance walked by the slower hiker in 10 hours  miles and the distance walked by the faster hiker in 10 hours

miles.

Given that, they were 77 miles apart in the beginning. So the equation will be

Answer:

400 red boxes were sold

Step-by-step explanation:

Step 1: Our output value is 2000.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above,2000=100%.

Step 4: Similarly, x=40%.

Step 5: This results in a pair of simple equations:

2000=100%

x=40%(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

2000/x = 100%/40%

Step 7: Again, the reciprocal of both sides gives

x/2000 = 40%/100%

x=800

Therefore, 40% of 2000 is 800

and to find 50% just divide by 2
